Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, particularly to orthopedics and can be used to determine extent of flat-valgus deformity. Method comprises clinical examination, evaluating symptoms of "prying fingers". Method includes measuring angle of rotation of lower leg and angle of heel pronation determine position of tuberosity of navicular bone in relation to Feiss line. Jack tests and "stand on your toes" test are conducted. Perform plantography and X-ray imaging of foot. According to X-ray image, determining Tara-I-metatarsal angle (TPPU), angle of heel bone (UNPK), angle of tara-navicular ratio (UTLS). Based on said data set determining degree of flat-valgus deformity. If on plantogram there is hyper-pronated type foot print, tuberosity of navicular bone lowered by no more than 1/3 of distance from Feiss line to plane of support, positive test Jack pronation angle of heel up to 10°, positive test, “stand on your toes,” absence of symptoms prying fingers, rotating tibia angle 13-15°, in largest TPPU lateral projection 5-8°, UNPK within 18-20°, 4 ° UTLS to determine degree I plano-valgus deformity, reflecting buckle foot. If on plantogram there is flattened type foot print, tuberosity of navicular bone, lowered by no more than 2/3 of distance from line to plane of Feiss support, positive Jack test, weakly positive test, “stand on your toes,” absence of symptoms prying fingers, an angle of rotation of lower leg 8-13°, pronation angle of heel up to 10°, value of TPPU side view of 5-8°, UNPK 17-14°, 4° UTLS to determine grade II plano-valgus deformity, reflecting a flattened foot. In presence on plantogram of plano-valgus foot print type, tuberosity of navicular bone, almost touching plane of support, pronation angle of heel in range 10-15°, symptoms of prying fingers and weakly positive test, “stand on your toes,” negative Jack test angle rotation of lower leg 4-8°, values of TPPU side view of 9-20°, UNPK 13-11°, 5-14° UTLS IIIa determine degree of flat-valgus deformity, reflecting compensated flat foot. In presence on plantogram of plano-valgus foot print type, tuberosity of navicular bone, almost touching plane of support, pronation angle of heel in range 10-15°, symptoms of prying fingers and negative tests, “stand on your toes,” and Jack test rotation angle shin 4° or less, in terms TPPU lateral projection 20-25°, UNPK 13-11°, UTLS greater than 15°determined IIIb degree plano-valgus deformity, reflecting decompensated flat foot. In presence on plantogram of valgus flat-type print circuit and a print head of talus, navicular tuberosity lying on a plane support, pronation angle of heel in range 10-15°, negative Jack and “stand on your toes” tests, dramatically positive symptoms prying fingers, angle of rotation of tibia values of 4° or less, TPPU in lateral projection of more than 25°, UNPK up to 10°, UTLS greater than 20° determine IVa degree of flat-valgus deformity, reflecting plano-valgus-withdrawn foot. In presence on plantogram of plano-valgus type print with an outline and print head of talus, tuberosity of navicular bone lying on a plane support, angle of pronation heel more than 15°, negative Jack test and “stand on your toes” dramatically positive symptoms prying fingers values of angle of rotation of tibia 4° or less, TPPU in lateral projection of more than 25°, UTLS greater than 25° a negative value and UNPK IVb degree of flat-valgus deformity, reflecting plano-valgus-withdrawn foot. 
     EFFECT: method enables accurate and simple determination of degree of deformation of foot by integrated assessment of most optimal clinical, plantographic, x-ray indicators.
